Description | PLLA is made from poly(L-lactide) and it has good biocompatibility, bio resorbability, biodegradability. After degradation in the body, the product is excreted by metabolism and it does not have harm and side effect to the human body. Therefore our products are currently widely used in the field of medical devices and microspheres for drug delivery etc. | ||
